Drive-by download is an unauthorized download of software from the internet to a user’s computer, usually without the user’s knowledge or permission. The term is derived from the phrase “drive-by shooting,” in which an attacker perpetrates a shooting on unsuspecting victims without ever leaving their vehicle. The same concept applies to a drive-by download, as the malicious software (malware) is delivered without the user’s knowledge or consent.
Drive-by downloads can be used to install malicious software, such as viruses, Trojans, spyware, adware, and ransomware, on the user’s computer. This malicious software can then be used to steal information from the user’s computer, disrupt operations on their machine, and cause other malicious activities. Some malware can even spread from the infected machine to other computers on the same network.
Drive-by downloads are generally delivered through exploit kits, which use various loopholes and vulnerabilities in browsers, software, and operating systems to secretly download malware to a user’s computer. The user does not even need to click on any links or open any emails in order for the download to take place.
To protect from drive-by downloads, users should install and regularly update antivirus software, use malware scanning software, and keep their operating systems updated with the latest patches and security updates. Additionally, users should exercise caution while browsing the internet, as malicious websites and webpages can be used to deliver drive-by downloads.
